Such separators areto which the lower end of the separator-rod is commonly employed. Theform of the sep ac adj ustably secured, the cross-shaft arm beingarators I do not herein claim, as separators partly broken away to showsaid supplemenof this form are shown, described and claimed tary arm,showing also means of adjusting the in United States Letters Patent No.496,186, parts which connect said separator-rod to said granted April25, 1893, to me. scparator-barto vary the distance between the Theseparator-bar J is preferably a round 9 5 45 extreme points of thetraverse of said separarod slightly flattened on the front or outer torsand the yarn-guides, showing, also said face i, to receive the bentinner end of the yarn-guides; Fig. 2, a vertical section on the shank iof the separator l, and to afford a line 22in Fig. 1, showinga left-sideelevation suitable bearing therefor. To the separator of a separator andthe devices which support, bar J the separators are secured by means of50 guide, and renderadjust-able said separators; screws 2' passingthrough slots 2' in the Fig. 3, a front elevation, and Fig. 4 a sideshanks of the separator and into or through the separator-bar J. Theseparator-bar J is supported in a socket L, (see Figs. 3 and 4,) havingupwardly -projecting cars Z Z, the front ears Z being curved outwardlyat their lower ends at Z to fit the curved surface of the separator-barand to prevent the separatorbar from rising in said socket when theseparators are turned up vertically from between the spindles in theoperation of dofiing. The socket-piece L is also provided with an upwardprojection Z at the back thereof and with avertical slot Z from the topof said projection Z to a point below the lower end of said projection,and one of the screws i extends entirely through the separator-bar intosaid slot Z and prevents any endwise movement of the socket L on theseparatorbar J. The socket-piece is providednear its lower end with atransverse horizontal slot Z to enable said socket-piece to be attachedby means of a bolt Z and nut l to the stoppiece M, said bolt passingthrough the hole on in said stoppiece, and the slot Z allowing thesocket-piece and stop-piece tobe adjusted laterally with respect to eachother in an obvious manner. The stop-piece M is provided at its upperend (see Figs. 0 and 10) with a forwardly-projecting and upwardly-curvedstop on, against which the shank of the sepa rator strikes when restoredfrom its vertical position to its horizontal operative position, thecurvature of the shank on the under side thereof where said shank joinsthe blade or body of the separator causing the separators in descendingto slide forward, drawing the separators J into the curvature Z of theears I, above described, and preventing said separat0r-bar from beingthrown upward in the socket by the weight of the attached separators.The lower part of the stop-piece M is provided with a vertical slot m(see Figs. 1, 2, 9, 10, and 11,) by means of which and by meaps of astud or (having about midway between its ends an annular collar or drawnagainst the front face of said stop-piece by means of a nut m turning onthe threaded rear end of said stud m against the rear face of saidstop-piece) said stop-piece is connected to the separator-rod N, saidseparatorrod having at its upper end an eye n through which passes saidstud m said eye being arranged in front of the collar m and being heldagainst said collar by a split spring-pin on, passing through a hole inthe front end of said stud in a well-known manner. The lower end of theseparator-rod N is provided with an eye a through which passes anotherstud 12?, which may be precisely like the stud m above described, saidstud n having a collar 01, and a nut or, by means of which collar andnut said stud is secured to the slotted supplementary arm f said studpassing forward through the slot f in said supplementaryarm up to saidcollar n and the nut 72 being turned up against the front face of saidsupplementary arm, and said eye a being retained on said stud n back ofsaid collar 0: by a split spring-pin f. The supplementary arm f isprovided at its inner end with a hook j, which engages the crosssshaft Iand near its outer end with a slot f through which passes the stud fabove described, said slot f being of sufficient length to enable thesup plementary arm to be applied to crossshaft arms f of diiferentlengths, and the slotted end of said supplementary arm being retained onsaid stud by a nut f which turns on the outer threaded end of said studf and holds said supplementary arm up against a shoulder f with whichsaid stud f is provided, as shown in Fig. 2. Bylocsening the nut a thestud a may be moved in the slot finearer to or farther from thecross-shaft F to vary the length of traverse of the separators. Theseparator-bar J is guided verti cally by a guide-stand P of the formshown in Figs. 7 and 8. Said stand P is provided with a horizontal slot13 through which a bolt 9 is passed into the roller-beam A, said slot 13allowing the guidestand to be adjusted laterally, to avoid the necessityof extreme care in making the hole for the bolt 1'). The guidestand P isprovided with two vertical guides 19 13, arranged at such a distanceapart as to receive and loosely fit the separator-bar J. The rearguide 1) is provided with a vertical. slot p which extends from thebottom of the guide to the top of the same to receive the projectingrear end of one of the screws and to prevent an endwise movement of theseparator-bar J, said last-named screw also acting as a stop and bystriking against the front lower end of said slot p holding theseparators in a vertical position in the opera tion of doffing. The rearguide p is offset forward at 13 just below the upper end of the slot 19to enable the separator-bar to be lifted out of said guide-stand P.

The projecting rear ends of the screws 1' which enter the slots p 1 areturned down to the bottoms of their screw-threads to produce lessfriction on the sides of said slots and to prevent said screws frombecoming loose in said slots.
